The Hex Bolt, also known as a Hexagonal Bolt, is a widely used fastener designed to join two unthreaded components with the support of a nut. HEX BOLT DIN 931 is engineered for high-strength applications, utilizing axial clamping force with a nut while the shank of the bolt functions as a dowel, securing the joint against sideways shear forces. These bolts are commonly used in assembly processes, where the corresponding nut can be turned when needed.
